Lost Songs - iPhone 4 update 4.2.1 - 1 iPhone, 2 computers

The usual solution to this problem is to simply sync your phone & your content will then appear correctly in your iPod app. However, in your case, this will not work as the computer containing your content is not available. If you try syncing to any computer available, your iTunes content on your phone is gonna be erased. This is one of the reasons why updating software on a computer other than the one you normally sync with is not a good idea...you don't have any good options should something go wrong.

You can try resetting your phone:

Press the sleep/wake button & home button at the same time, keep pressing until you see the Apple logo, then release(ignore the slide to power off).

If that doesn't work, I know of nothing else to suggest other than syncing to the computer you normally sync with(obviously not an option in your case).

Seems weird that an update would have this affect though

I agree, & have noticed it in several iPhones I've updated as well as a number of user postings. The fix is relatively easy, but unfortunately not available in your case.

My last suggest would be to download, directly on your phone, any song from iTunes, even the free song of the week. Then, play that song & see it doing this fixes your issue.

I have the same problem. I updated my iPhone 4 last night and this morning while on my way to work was unable to access my songs. The phone recognizes that the songs are there, but they do not show up in the iPod. This is my second iPhone. Before I bought this one, I had an iPhone 3G. After updating it to 4.0 I had problems that could not be fixed. I was told that all the 3G devices ran slow on the new update. Right now, with my iPhone 4, all I have is a high priced phone with NO features. I have several iPods and the reason I purchased the iPhone was to combine the two devices. I recommend that before Apple releases another update be sure that it works properly.

your correct about it being buggy code this problem has come up a million times and the only way to fix it is to sync with the computer that has your music it wont actually copy it all back but it will make it show up it ***** but thats the only way..

Your songs are not lost, simply connect iPhone to any PC and within iTunes play a song or a video to hear or watch on your PC for a few seconds. Afterwards you will them see your ipod content on your iPhone again. I agree this is a buggy update but the iPhone is still the best.

Ran into this issue also. I just plugged the iPhone back into the Mac and did another Sync. All the songs then showed up in the iPod app.

The heck with Re-Synching that takes too long, playing a song or a video thats on the iPhone from within iTunes is quicker. Just takes a few seconds and your done.

Since the sync from the night before had everything, and nothing had changed on the iPhone, the sync only took about 10 seconds.

Omg that was so easy to fix. Thanks for the post!!

I had the same problem with my iPhone 4 after the 4.2 update, but after a quick sync, everything was restored satisfactorily.

Always good advice to do a quick backup before doing any major overhaul to your phone's soft/firmware.
