So i've got the new iPhone 3GS with 3.12 and I jailbroke it with blackra1n and unlocked it at the same time because I needed to use my old gsm sim. (number was transfered and took about 1 week) SOOO I then got the new sim card with 3G and it works BUT if i've got a weak signal (1-3 bars) the connection is dropped and sometimes the phone even gets stuck for like 30s. I've asked my friends with the same iPhone, same location and same operator (no one has blacksn0w) and they haven't experienced it. The questions/fixes are: -should I restore? (I would like to wait for 3.2 or a full jailbreak before doing it) -Can I somehow uninstall blacksn0w if it is causing it? -Is it hardware (good god NO!) Help would be appreciated, thx.
