For those of you wondering what the Sidekick 3 OTA that is currently rolling out brings to your device, wonder no more:
* GSM network feature enhancements
* Enhanced USSD Support
* Retry option for failed Text Messages
* Enhanced SIM PIN protection
* Optimized PLMN scan algorithm to improve network registration time when returning to good coverage
* Faster PLMN searches
So in short about the only thing you’ll ‘see’ is better coverage and the ability to resend text messages when they fail.
