Yes if youre previous backup is from OS 4.1 then you'll have to update the IP4 fw to 4.1 to restore from backup, I encountered it as well but the download and update went through and synced my backup..Voila! carbon copy of my 3GS!


thats odd the first thing i did was the death grip and no line drops on mine, im using Maxis. Tried it in Gardens it worked, Tried back home in my place in PJ it works, just tried it in Cyber it works NO line drops maybe 1 bar give or take, but not the astonishing drop that ive seen on the Net or Youtube

How do you determine if you are on GSM 900 or UMTS 2100? care to explain? yup im on Maxis

yes you can

If you use Bumper or any case no reception issue at all.

If you're on a 2G network in layman terms. you turn OFF your 3G and turn ON the cellular data you're already on 2G network No Death Grip issue's

If your on an EDGE network, meaning you turn OFF your 3G and turn ON the cellular data 1 bar drop can be seen

If your on an 3G network, meaning you turn ON your 3G and turn ON the cellular data 2-3 bar drop can be seen

based on the above make your own computation's depending on the coverage area you're in. for example you're in a poor coverage area on a 3G network you put the phone in a Death Grip yes of course you'll end up with a NO SERVICE

thats odd i typed your same question in Google i got my answer.
