So after a nonstop apple logo screen I got a replacement. One I got home I restored and it worked good. Installed a new app and bam, locked up my iphone and could not recover and had to restore. I had my 2nd iPhone for 3 days and restored 4 times. YES restored 4 times. Tonight I deleted all the apps from itunes and restored again. Worked perfectly. Now slowly installing apps. Install one , disconnect the iphone , reconnect and sync up. If no issues I install one more app. So far so good. I have installed 6 of my 30 apps. Iam starting to think that some apps may contribute to my main issue of locking up while instaling. Luckily I havnt locked up yet since but I am getting more gunshy of installing apps. Could it be that one or more of the apps is doing something to the firmware that is corrupting it for future app installations? I have currently on my iphone...five dice, bejeweled 2, netnewswire, labyrith LE, sudoku and Cube runner. Installed flawlessly and works fine. I want to keep installing but so afraid of locking up again because makes me restore and then thats an hour or more without my iPhone. Thoughts?
