If this has been posted already, I apologize. Do ALL the steps. Do not skip a single one: 1) Bring up iTunes 2) Edit/Preferences, Click on the last tab, sync, and disable auto sync for all iPod and iPhones. This does not fix it it is just the first step do not stop here. 3) Next connect your iPhone to the computer. 4) Once it shows up in iTunes go into the last tab Applications. 5) Uncheck sync all apps. 6) Click apply. 7) Now click sync and it will remove all the applications from your phone. Don't panic. This is expected and wanted. 8) After it is finished unplug the iPhone. 9) I bet you will have at least one app still on the Iphone, maybe more. 10) Hold any icon down until they jiggle. 11) Tap the x's and delete all the remaining apps. 12) You may notice after you delete each app that a little spinning circle is next just to the right of your signal icon. Let it finish spinning before you delete the next app. 13) Once you have deleted all the remaining apps (That had corrupt data that was causing your long back ups!) do a hard reset. To do this hold the sleep/wake button and the home button until the red slider appears at the top of the screen. Slide it over and the phone will power off. You will again notice the spinning circle. Once it finishes wait a few seconds and power the iPhone back on by pressing the sleep/wake button. 14) While it is booting back up go into iTunes again turn the auto sync back on! 15) Now connect the iPhone to the computer, let it backup and sync. It should be much faster. 16) Now after it finishes go back to the applications tab. 17) Click sync apps again, but make sure you have the 2nd circle checked. This box is sync selected apps. Make sure all the boxes are unchecked! 18) Now slowly begin adding apps back to the iPhone. No more than 5 at a time. Check the boxes then click apply, then sync. Then add a few more, click apply, then sync. Repeat until all apps are on that you want. It will backup then add the applications and sync all other information. Here is the kicker! DO NOT update or install apps from the phone! Only use iTunes to install and or update apps until they get the bug fixed!
