I try to explain as best as I can:
I'm using an italian SIM in my iPhone 2G with QuickPwned 2.2 firmware. Since the upgrade from 2.0.1 to 2.2, I miss sending SMS from Italy. This are the scenarios: when in Italy, I can't send SMS (Error sending message, but how to debug further?). When I'm abroad (Switzerland, for example) and I'm in roaming, I send SMS without troubles.
I thought it could be because EDGE was enabled in Italy, therefor I used BossPrefs to disable it (and I also deleted the default APN to assure that no EDGE will be used). That wasn't the solution to my trouble, so... WHAT NOW? Any help?
Thanks in advance,
