In the past, upgrading your older iPhone model to the latest OS release is a no-question decision. With Apple's latest iOS 4, however, you may want to keep your old setup instead.
Why? For the most part, news we heard from folks still using their 2G and 3G devices isn't all that favorable, with users reporting issues such as:
- Slow speed. Yes, many people are reporting that iOS4 turns their older iPhone models into a laggy device.
- Lots of absent features. The slower operation might be an acceptable trade off for the spanking new features, but too many of them just aren't available even with last-gen devices - more so than originally advertised.
- Voice and messaging problems. We're not sure what's causing it, but some users have reported being unable to use either their handset's phone or messaging functions with iOS 4 in tow.
- Some of your apps won't work. This will probably be fixed in due time after updates from the developers themselves. If one of those apps turn out to be crucial to your day-to-day business, however, you're screwed.
If you'd still like to try (let's face it, we all want to), it's unfortunately not as easy. Most people are reporting installs that take very long, so prepare to keep both your phone and computer busy with that for at least an hour or so (some users are reporting up to over three hours, but that may be the exception, rather than the rule).
Of course, direct installs don't work for everyone. It would be too easy if it did, and where's the fun in that? In that case, your likely best bet is to do an update and restore. If you're not sure how to go about it, here's a quick rundown of the steps:
- Upgrade your iTunes 9.2 to be ready for iOS 4.
- Back up all your apps and data.
- Once backup completes, click Restore in iTunes, which will refresh your device to its original state, then perform a firmware update to iOS 4.
- When that's finished, restore all your apps and data from the earlier backup.
Good luck and don't worry - we haven't heard about anyone bricking their phones yet, so it's probably safe.
