So far an iPod Touch or an iPhone running firmware 2.0x could face some serious problem with application management. Beside crashes, one can also list:
- Never ending procedure to save a document on the handheld.
- Difficulties to perform updates directly from device on the AppStore.
- iTunes refuses installation of application for any reason.
The new firmware 2.1 seems indeed to fix most problems and it might well be the best update for most users, and you should get it as soon as it will become public on Friday. Apple probably decided to make it available at the end of the week to spread the server loads associated with such procedure over the week-end.
