My Iphone 4 has IOS4.1 I can not get it updated with out crashing
I am very new to Iphones. I have an Ipone 4 with IOS 4.1. I have tried to update it but it keeps Crashing and locking up my phone.
Any help would be appreciated. No matter what I try to install always asks for at least an IOS of 6
Thanks
