Guys my iphone accidently went to recovery mode and after that i have to restore it to the latest firmware i.e 4.3.5 i have sucessfully updated my iphone 4 and have also unlocked it with gevey sim. But now the deal is that I am unable to find personal hotspot any where in my iphone nor I can find MMS option under settings>message. What should I do to use personal hotspot on my iphone 4 and also the MMS services. And also while updating i have removed the gevey sim and have inserted the original at&t sim inside and after updating i was able to see both personal hotspot and MMS options but after gevey sim unlock i can not find them any where. Hope for some help soon. Thank you.
