Updated to 2.1 tonight (non-rooted, unbranded X10i) and so not impressed. 1) Scrolling through screens and menus is so jerky. Phone seems slow in switching between apps too. 2) Backup / Restore: I did the "Back-up" as recommended. When restoring the contacts status gets to "Processing 99%" and no better! When I just used the "Home" key to get out of it and looked in the Phone book, I reckon only about 25% of contacts were there. Have just done another restore and no change. 3) A lot of software does not appear in market "Download". Strangely, when I first went into that part of the market and scrolled through, I'm sure all the bits of software I'd downloaded on the phone originally were there. However, having started to download again from the top of the list, I eventually ran out of apps to download, way short of the full list. Where did they go? I found most in market again with a manual search, but that wasn't perfect. For example, I'd paid for Ultimate Juice Defender on my phone, but it doesn't list as "Purchased" (i.e. asking for me to pay again). That's it for now. Anyway, far from happy with this update.
