I have an iPhone 4 locked on the 02.10.04 bb and unlocked with gevey SIM. 3G is not working at all, my phone is working on EDGE. My carrier is promissing more than 7mbps and I barely get 0.2mbps. They sent me the APN which I was supposed to write baseband and nothing else in the other fields. I also tried these methods: -resetting network settings -resetting all settings -tried the unlockit website with custom APN -hard and soft reset -took my bicycle and tried connecting to 3G in multiple spots in my city I didn't try restoring it to factory settings and setting it as a new iPhone because I'm not the first owner of this iPhone and I never set it as a new iPhone. I will do that when I'll come back home but I need to know if there are other methods that I should try. (also, please, avoid telling me to get an iPhone replacement or call Apple because there is absolutely no Apple store in my country). I bought this gevey SIM from someone from a local forum. I tried his gevey sim in my iPhone with his carrier SIM (I noticed we're on the same carrier - Cosmote Romania) and the 3G appeared next to the carrier name but after I unlocked it on my iPhone, I only see EDGE, the 3G never turned on.
