I have a 2g iphone 1.1.4. My last download was pocket guitar, after which i switched off phone( held sleep wake button for 5 secs, then a slide power off). Upon trying to power up again, i see only the apple logo, nothing else happens till power drained off. if i hold sleep/wake and home buttons simultaneously for more than 7 secs, it powers off again. nothing else happening. i have softwares iSMS, ilog and SIMport installed besides some games etc. I have itunes version 188.8.131.52 installed, and that does not show iphone connected. this has been an old issue, much before i installed all the apps. Please advice what i can do to restart the phone.
