please help!! iphone will not boot!!

[bjunwei]

my iphone 3gs, running ios 4.0, cannot be turned on now. once i try to turn it on, the apple logo shows, then it disappears after about 2 mins and appears again, the cycle repeats. I've already put my iphone into and out of recovery mode, as well as into and out of dfu mode, but the phone just will not turn on.

i havent tried restoring because i do not want to lose my photos and smses. please help me out here!! either to get the phone turn on WITHOUT restoring. or to get the smses out of the phone into the computer, after which i don't mind restoring. please help!! thank you in advance!!!

When was the last time you synced it with itunes?

[bjunwei]

on the 31st of 2010, which is about 20 days ago.

[Simon]

If you plug it in are you able to see the file system at all with something like iphonebrowser or ifunbox?

[bjunwei]

no i cant see it with iphonebrowser but when i previously set it to recovery mode and dfu mode, itunes senses it.
and i online tool to get my backedup smses from 2010 into a file, so all im missing now is this year's smses!

[Simon]

If you cant even access the file system sorry to say restoring may be the only course of action.
