How to upgrade iOS to new version on 3gs
Hi,
I want to upgrade iOS on my 3gs iPhone from 4.3.5 to 3gs supportable version,
is it possible to upgrade because non of the apps supporting..?and which version will it support..?after upgrading mobile will process slowly...?
I came to know that we can't downgrade once we upgrade to latest versionin 3gs mobile ios...is it true..?
Please help me since am facing lot of problem am unable to use all apps because of iOS is not supporting.
Thanks
