HI, I have bought the Xpheria X10 about 8 months ago, I live in Canada, and am on Rogers Wireless 3G, Rogers service is great, I love the phone the only down fall was battery life which semingly increased a day with the new droid upgrade to 2.1. NOw since that upgrade the Con's are out weighing the Pro's CON'S #1 My phone Contacts will not work threw the phones OEM software Contact list, I had to D-load an "app" contact book just to call my contacts, big pain in the but really. Strange thing is in my OEM contact list works with the text messaging!!! #2 My phone has this lovely feature of selective ringing, it decides to ring only sometimes and others not, I miss ALOT of calls, and I dont have that nifty option checked to send calls to voicemail so dont ask! #3 There is another new thing my phone likes to do, when I try and call someone (anyone) I press the call button, and it says, "connecting..." for all of 2 seconds then says "call ended" repeatedly until it decides to let me complete a call, and I have turned my phone off, and on, and removed my case, battery, sim card, and nothing matters until it decides to let me complete a call. #4 My phone has slowed down ALOT since the upgrade, I don't D-load a ton of apps, I make sure the ones I use are closed properly, not just backed out. I have a task killer which only runs minimal background apps if any, but yet it has lost well over 50% of its original speed. Oh and I have clear caches at least the ones I have found in the phones limited options menu. So in short I am hoping either someone has come across these issues and fixed them and can address each of my issues, or someone can tell me how to revert back to ver 1.6 please. I like the phone, I don't like the new software upgrade, it looks nice but cant walk the walk. Please don't make me regret not getting an "I phone"! Thx for your feed back.
