摘要:
A portable wireless user communication device is wirelessly coupled to a second device over a monitored link. If the link is lost or endangered, then a user alarm is activated at the portable wireless user device and/or at the second device to which it is linked (which may also be a portable electronic device). The type of monitoring and/or the type of alarming may be user selectable.

Systems, devices, and methods for modifying a signed bundle and verifying the modified bundle are disclosed. A signed bundle may be modified by removing a file specified in a server file list from a plurality of files in the bundle. The signed bundle comprises a catalog of files in the signed bundle and their associated hashes. The modified bundle includes the remaining files of the signed bundle that are not specified in the server file list and the catalog file of the signed bundle, the catalog signature of the signed bundle. The modified bundle may be verified by verifying the catalog signature of the modified signed bundle, and checking that the files specified in the catalog are either in the modified signed bundle or specified in the server file list. The hashes of the files in the modified signed bundle may also be checked to verify the modified signed bundle.

A hand-held electronic device is provided having a keyboard optimized for use with the thumbs and an inclined thumbwheel for auxiliary data entry and selection. The keyboard preferably includes a plurality of non-uniform shaped keys, such as oblong, oval or rectangular keys, which are organized into two sets of keys that, together, form a QWERTY keyboard. The two sets of non-uniform shaped keys are tilted at complimentary angles to each other and with respect to a common vertical reference through the device. The keys are also uniformly distributed across the device to facilitate optimal thumb typing. The thumbwheel is inclined at an angle for easier operation, and is used for auxiliary data entry and menu selection.
