Iphone 4 hardware unlocked on T-mobile, should i & how can i upgrade?

philipxcui · Dec 5, 2011

I brought my iphone 4 at a T-mobile retailor n it is hardware unlocked running on ios 4.3.3. At first the msg couldnt send pic but i fixed it by watching youtube. When i get the phone the retailor specific told me not to update my ios. I had been very careful of not trying to update it. First of all, I have a app called Furious Mod on my phone n i have no clue what it is.... Secondly, the option jumps out sometimes ask me to accept furious mod, n the phone says No SIM when restart sometimes. Why is dat? Also, I need to know if i can upgrade my ios 4.3.3. to ios5.0.1 or later version n how.

Please help me here.

P.S. I think the hardware unlock might be gevey, i never taken out the sim tray.

So what you're saying is that you have purchased a GSM iPhone from an actual T-Mobile store? Not to be facetious here... but I find it hard to believe that an "authorized" T-Mobile retailer to sell you an unlocked GSM iPhone.

You can upgrade to 5.0.1 but you would have to PRESERVE your baseband is order for your iPhone to be unlocked also in order for furious mod to work you need GEVEY SIM ULTRA
