How to fix some mysterious problems.

everytime i run GP something goes wrong and my phone goes into safe mode and i have to restore it on itunes... ive had a JB iPhone since the iPhone 1... i know how to do it and have never had a problem... im running IOS 4.2.1 on an iPhone 4 i ran GP and the first time i assumed that one of the cydia programs was crashing the sub-strait(?) and putting it into safe mode... i ran the 2 programs you recommended to see what was causing the crash and nothing came up... so i restored and ran GP again... this time it didnt keep my aptbackup and i had to go thru cydia and dl some of the apps i had... dont remember them all... sux... so i was looking thru my pages and the installer was still there so i went into it and deleted it thru the app since i had cydia and was already running apps... and then it crashed again and im now in the middle of restoring it again... please help... ill do what ever you need me to do... but this s$!t has to stop... i need my phone and am sick of the hour to restore it... ugh... :/

What's the size of the iPhone3,1_4.2.1_8C148_Restore.ipsw file? 654.6MB is what I get, just in case it's incomplete or something weird.

Also, are you restoring a backup from iTunes? Maybe something in there is corrupted?

Just some ideas.

You're asking how to find the size of a file? I'm talking about the size of the ipsw. You downloaded it before you could restore. Or if you let iTunes download it for you it should be on your HD.

Search for the file iPhone3,1_4.2.1_8C148_Restore

Are you on a mac, or PC?

On a Mac, this file will be in: /Users/<your_user_name>/Library/iTunes/iPhone Software Updates/

On Windows, the file will be in "Documents and Settings\<your_user_name>\Application Data\Apple Computer\iTunes\iPhone Software Updates"
