I claim: 1. A method of input and fingerprint recognition at an electronic handheld device, the method comprising the steps of: providing a touch surface having a touch resolution portion and a fingerprint resolution portion distinct from the touch resolution portion, the touch resolution portion and the fingerprint resolution portion being integral to said touch surface, and the touch resolution portion having a touch resolution for detecting a touch input on said touch surface; and selectively operating the fingerprint resolution portion in one of a fingerprint mode for sensing a fingerprint on said touch surface and a touch input mode for detecting the touch input on said touch surface. 2. The method according to claim 1, wherein the selective operating step comprises detecting activity at the fingerprint resolution portion as navigation data in the touch input mode, and detecting activity at the fingerprint resolution portion as fingerprint data in the fingerprint resolution mode. 3. The method according to claim 2, wherein in said fingerprint mode the fingerprint resolution portion is sampled at a fingerprint resolution rate providing the fingerprint resolution portion with a resolution sufficient for sensing the fingerprint on said touch surface, and in said touch input mode the fingerprint resolution portion is subsampled at a rate less than the fingerprint resolution rate, said subsample rate providing the fingerprint resolution portion with a resolution sufficient for detecting the touch input on said touch surface. 4. The method according to claim 3, further comprising the step of recognizing the fingerprint on the fingerprint resolution portion in the fingerprint mode. 5. An apparatus for input and fingerprint recognition on a handheld electronic device, the apparatus comprising: a touch surface having a touch resolution portion and a fingerprint resolution portion distinct from the touch resolution portion, the touch resolution portion and the fingerprint resolution portion being integral to said touch surface, the touch resolution portion having a touch resolution for detecting a touch input on said touch surface; and a data processor coupled to the touch surface and being configured to selectively operate the fingerprint resolution portion in one of a fingerprint resolution mode for sensing a fingerprint on said touch surface and a touch input mode for detecting the touch input on said touch surface. 6. The apparatus according to claim 5, wherein the data processor is configured to detect activity at the fingerprint resolution portion as navigation data in the touch input mode, and to detect activity at the fingerprint resolution portion as fingerprint data in the fingerprint resolution mode. 7. The apparatus according to claim 6, wherein the data processor is configured to sample the fingerprint resolution portion in said fingerprint resolution mode at a fingerprint resolution rate providing the fingerprint resolution portion with a fingerprint resolution for sensing the fingerprint on said touch surface, the data processor being further configured to subsample the fingerprint resolution portion in said touch input mode at a rate less than the fingerprint resolution rate, the subsample rate providing the fingerprint resolution portion with a resolution sufficient for detecting the touch input on said touch surface. 8. The apparatus according to claim 7, further comprising a housing, the touch surface and the data processor being disposed within the housing, the housing being configured for releasable attachment to the handheld electronic device. 9. The apparatus according to claim 8, wherein the housing has a communication interface at one end thereof for interfacing with the handheld electronic device. 10. The apparatus according to claim 9, wherein tile, the housing has a shape corresponding to that of the handheld electronic device. 11. The apparatus according to claim 10, wherein the handheld electronic device includes a display screen on one side thereof, and the touch surface corresponds in shape to the display screen. 12. A handheld electronic device, comprising: a display screen; a keyboard; a touch surface having a touch resolution portion and a fingerprint resolution portion distinct from the touch resolution portion, the touch resolution portion and the fingerprint resolution portion being integral to said touch surface, the touch resolution portion having a touch resolution for detecting a touch input on said touch surface; and a data processor coupled to the display screen, the keyboard and the touch surface and being configured to selectively operate the fingerprint resolution portion in one of a fingerprint resolution mode for sensing a fingerprint on said touch surface and a touch input mode for detecting the touch input on said touch surface. 13. The handheld electronic device according to claim 12, wherein the data processor is configured to detect activity at the fingerprint resolution portion as navigation data in the touch input mode, and to detect activity at the fingerprint sensor resolution portion as fingerprint data in the fingerprint resolution mode. 14. The handheld electronic device according to claim 13, wherein the display screen and the keyboard are disposed on one side of the handheld electronic device, and the touch surface is disposed on a side of the handheld electronic device opposite to the one side. 15. The handheld electronic device according to claim 14, wherein the data processor is configured to sample the fingerprint resolution portion in said fingerprint resolution mode at a fingerprint resolution rate providing the fingerprint resolution portion with a fingerprint resolution for sensing the fingerprint on said touch surface, the data processor being further configured to subsample the fingerprint resolution portion in said touch input mode at a rate less than the fingerprint resolution rate, the subsample rate providing the fingerprint resolution portion with a resolution sufficient for detecting the touch input on said touch surface. 16. The handheld electronic device according to claim 15, wherein the handheld electronic device is a wireless device.
