My phone's giving me a hard time already with apps crashing, so it's time to reset to factory defaults anyway, but I'm also kind of curious about following that up with an upgrade to ICS.
My questions are:
1. Is it possible to upgrade directly to ICS using Clockworkmod (v. 2.5 is already installed) by selecting the ROM zip that's on my phone? (I don't care about the data on the phone except my phone book which is sync'ed with Kies)
2. If not, can I upgrade to the latest ROM available on Kies (2.3.6 "value pack", I believe) and then upgrade to ICS using the newest version of CWM?
as long as you are rooted and have a version of CWM that will allow you to wipe cache, wipe dalvik cache and factory reset/wipe user data and then flash a zip file, you should be fine. Do those things in that order and then do the wipes and factory reset again before booting into ICS. You may also need to install the latest Google Apps for ICS, you can find these in lots of these forums, search for GAPPS for ICS.
It's worth bearing in mind that the ROM you are going to use could be an MTD ROM which means that it changes the partition structure of the internal memory. You get more apps in the phone memory, basically. Becuase of this it is more difficult to go back to Gingerbread or Froyo etc. It can be done but requires the use of Odin and a 're-partition' which could mess up your internal memory.
There is also the CM9 Nightly build now available for I9000 which I am using. It's very good.
