I have just bought a new N900 and it has PR1.1.1 installed. Should I update to PR1.2? I can see there are quite a few threads about problems with PR1.2. Is the general consensus that the update is good and these problems aren't seen by many?
If I stayed with PR1.1.1 would it affect my ability to install or update new apps?
Also what it the recommended way to install PR1.2? Uninstall all apps and update with OVI? Is it ok to do it OTA?
definitely upgrade. not only it fixes a lot of bugs in pr1.1.1, but it also allows access to the ovi store (not that there's too much in there at the moment but... ). not so many problems with it, a lot more with 1.1.1. also, 1.1.1 lacks qt4.6 required for new apps, so..
if you do it OTA (simplest) it might take a while. you don't need to uninstall anything and all your settings are kept.
if you flash it it's gonna take less, but you will have to reinstall your apps.
It's definitely worth an upgrade. Going by forum posts you'll find they're heavily skewed towards negative experiences because the thousands of people who upgraded without a hitch probably won't have the need to post about it, so don't let that scare you off.
