I recently bought an unlocked Sidekick 3 on ebay. The phone worked fine, the only thing I noticed was that I couldn't use any of the data services on my AT&T network. Now I'm considering buying an unlocked version of the Blackberry Storm (or the locked and unlock it myself) and I was wondering if anyone knew if i would have the same problem with the data. Blackberrys are known for their email and browser things so I probably wont buy it if I am unable to use the data services. Thanks a bunch!
