I'm getting this error with the iPhone I was given when my original white 3G phone cracked.
Unkown Error On The iPhone | DamienKomala.comDamien suggests selective installation (see post for details). This worked for me:
... Ok so every time I try and update or upgrade an application on my iPhone I get this “Unknown Error: 0xE800002E. After some adjustments I was able to find a method to resolve, or at least update my apps. Here’s the key ...
- Delete app from iPhone
- Delete app from iTunes
- Click to download. iTunes says I already own the app, offers to redownload.
Update 8/11/08: I'm now seeing the same error with every application update that appears. I think that either my iPhone has a hardware bug or restore from backup doesn't work properly. I hope, and suspect, it's the latter.
This time I tried Damien Komala's tip. I deleted the app from the iPhone, then did a selective app sync with the app unchecked, then checked it.
