I am getting ready to release my application on AT+T with RIM signing. AT+T makes a big to-do about API restrictions and signing requirements for their Java apps on Java phones and seemed to imply it was required for Blackberry applications as well. I have found this not to be the case, RIM signing gives me access to all the needed APIs without any carrier restrictions. I'd like to release the application for my customers that run on other carriers (like Verizon/Sprint), but I wonder if they add additional restrictions or is RIM signing enough (like it is for AT+T). Can someone share their experiences with other carriers? Thanks!

Your BlackBerry Developer's signature will work with all carriers. I have read in the APIs that AT&T also has some custom signature requirements around GPS but we have not run into this restriction. Everything else is pretty much the same across carriers. The main things that do vary across carriers are:
1. How SMS is sent/received programatically
2. The default application permissions
3. APN information for making WAP connections

Although the API docs do mention that AT&T requires separate signing, they never implemented it. I've got 2 AT&T test devices and have full access to the location APIs.
