A method, apparatus, and computer instructions for a communications device transferring data. A signal strength is received for a communications link used to transfer data to a destination. In response to the signal strength less than a threshold, the data is cached in the communications device to form cached data. In response to a loss and reestablishment of the communications link, the cached data is sent to the destination.

What is claimed is: 1. A method in a wireless communications device for transferring data, the method comprising: receiving a signal strength for a communications link used to transfer data to a destination; responsive to the signal strength for the communication link being less than a threshold and the communication link is still maintained between the wireless communication device and the destination, caching the data in the wireless communications device to form cached data and generating a warning indication; responsive to the caching of the data, receiving another signal strength for the communication link; responsive to the another signal strength for the communication link exceeding another threshold that is below the threshold, halting the caching of the data; responsive to the another signal strength for the communication link not exceeding the another threshold, determining if the communication link has been lost, and if so, determining if the communication link has subsequently been reestablished; responsive to the subsequent reestablishment of the communications link, sending the cached data to the destination, wherein the sending step includes prompting a user of the wireless communications device to indicate whether to send the cached data to the destination and, responsive to a user input to send the cached data to the destination, sending the cached data to the destination, wherein the sending step further includes (i) discarding the cached data in an absence of the indication to send the cached data to the destination, and (ii) discarding the cached data responsive to the signal strength for the communication link exceeding the another threshold. 2. The method of claim 1, wherein the data is at least one of voice data and text data. 3. The method of claim 1, wherein the wireless communications device is one of a mobile phone, wireless personal digital assistant, or a laptop computer with a wireless adapter. 4. A wireless communications device for transferring data, the wireless communications device comprising: receiving means for receiving a signal strength for a communications link used to transfer data to a destination; means, responsive to the signal strength for the communication link being less than a threshold and the communication link is still maintained between the wireless communication device and the destination, for caching the data in the wireless communications device to form cached data and generating a warning indication; means, responsive to the caching of the data, for receiving another signal strength for the communication link; means, responsive to the another signal strength for the communication link exceeding another threshold that is below the threshold, for halting the caching of the data; means, responsive to the another signal strength for the communication link not exceeding the another threshold, for determining if the communication link has been lost, and if so, determining if the communication link has subsequently been reestablished; sending means, the subsequent reestablishment of the communications link, for sending the cached data to the destination, wherein the sending means includes prompting means, responsive to the loss of the communication link and the subsequent reestablishment of the communications link with the destination, for prompting a user of the wireless communications device to indicate whether to send the cached data to the destination and sending means, responsive to a user input to send the cached data to the destination, for sending the cached data to the destination, wherein the sending means further includes (i) means for discarding the cached data in an absence of the indication to send the cached data to the destination, and (ii) means for discarding the cached data responsive to the signal strength for the communication link exceeding the another threshold. 5. The wireless communications device of claim 4, wherein the data is at least one of voice data and text data. 6. The wireless communications device of claim 4, wherein the wireless communications device is one of a mobile phone, wireless personal digital assistant, or a laptop computer with a wireless adapter. 7. A computer program product in a computer recordable-type media for a wireless communications device transferring data, the method comprising: first instructions for receiving a signal strength for a communications link used to transfer data to a destination; second instructions, responsive to the signal strength for the communication link being less than a threshold and the communication link is still maintained between the wireless communication device and the destination, for caching the data in the wireless communications device to form cached data and generating a warning indication; third instructions, responsive to the caching of the data, for receiving another signal strength for the communication link; fourth instructions, responsive to the another signal strength for the communication link exceeding another threshold that is below the threshold, for halting the caching of the data; fifth instructions, responsive to the another signal strength for the communication link not exceeding the another threshold, for determining if the communication link has been lost, and if so, determining if the communication link has subsequently been reestablished; sixth instructions, responsive to a loss of the communication link and the subsequent reestablishment of the communications link, for sending the cached data to the destination, wherein the third instructions includes first sub-instructions, responsive to the loss of the communication link and the subsequent reestablishment of the communications link with the destination, for prompting a user of the wireless communications device to indicate whether to send the cached data to the destination and second sub-instructions, responsive to a user input to send the cached data to the destination, for sending the cached data to the destination, wherein the sixth instructions further includes (i) sub-instructions for discarding the cached data in an absence of the indication to send the cached data to the destination, and (ii) sub-instructions for discarding the cached data responsive to the signal strength for the communication link exceeding the another threshold. 8. The computer program product of claim 7, wherein the data is at least one voice data and text data. 9. The computer program product of claim 7, wherein the wireless communications device is one of a mobile phone, wireless personal digital assistant, or a laptop computer with a wireless adapter.
