RIGHT...... I bought a secondhand iphone 3g 8gb (MB model) afew weeks ago, already updated to 4.0. The phone was majorly lagging so i went about trying to downgrade. After a tonne of errors and pulling my hair out, i finally managed to get it to downgrade to 3.1.3. The phone is now running perfectly..... However........ When i connect it to itunes it syncs but as its backing up a box appears saying: Itunes could not backup the iphone 'cb3g' because the iphone disconnected. but it isnt disconnecting at all Please Register or Log in to view images I'm using iTunes 9.2 with 3.1.3, would that make any difference? Would it be worth trying an older version?
