Exactly the same problem here after an "upgrade" to ios6.
When trying to access the "purchased" section of iTunes/music store (which shows a massive 121 tracks...) we get the spinning wheel of death before the iTunes/music store app eventually crashes. Other non-upgraded devices are okay. It seems strange that such a bug wasn’t discovered during pre-release testing however it would be nice to see an official Apple response and acknowledgement of a problem.
Personally, if there are bugs discovered, I’d have far more respect and would far rather if vendors (not just Apple) would hold their hands up and officially say “yes, we’ve got it wrong, don’t worry it’s not a problem with you, we are working on it” and then give an indication of time to fix. Problems happen, it would just be nice to know that someone is working towards a resolution.
However, I fear what’s more likely is that a new code drop will eventually be released (marketed of course with some positive spin of other “must have enhancements”) that just happens to fix the issue. After all… if you keep quiet it’s less likely to damage reputation.
Combined with the farce that is ios6 maps I wish I hadn't bothered “upgrading” this device… I will definitely not be upgrading my other devices anytime soon 😉.
Climbing off my soapbox now....
