Well I bit the bullet and gave the update a go. I took two tries. Backup failed on photos and stalled taken 15min /per photo. Then, I cancelled the backup and it went to do the updated. Decompressing files downloaded etc but hung up before switching to upload to the phone. Phone never toggled into download mode (Yellow warning the screen) which I saw at the end in the 3rd attempt.
All in all. The results were.
- all apps remained (built in and installed market apps)
- configuration of connections and all data remained intack
- memory card content appear unaffected (no surprise there)
My phone is still sluggish and I am not certain what I've gained other than its more secure than the Froyo version. If you run RU@RISK in Froyo you're vulnerable. In GB you're not so thats good step even though 2.3.4 is more secure and fixed some bugs.
