Here are the list of cons I can come up with
I don't know about all your issues but I have this phone for a few months and it sure is rock solid the best phone in my experience, Forums and blogs rate it at a very competitive level with the Iphone with some saying its even better the the iphone.
As far as your problems go, I would say that your not updated with the firmware, try to update and see if all these problems will still be nagging you. I have the same exact phone with sprint and have none of these issues u mentioned.
Go to Settings/About phone check if you have android version 2.3.6
1> When I get a text or email theres no 1 on the icon. I have a 1 on text, on email you will only get a 1 on the email app but not on the gmail app.
2>How to save skype password and not have to manually enter it in each time. My other android/apple phones did it automatically.open skype go to settings first thing on top is sign in automatically, check that, (you also have this option every time you sign out you will see this:"Exit and sign me in when skype starts?" check that too)
3> A decent unlock screen widget? I downloaded a widget which makes you draw a pattern to unlock ...ok but cud do alot betterNo need to download a widget as it comes built in to phone, go to settings/location and security scroll down to screen unlock settings check use visible pattern.
4>wifi signal very weak. in my experience its much better then other phones, it connects in less then 2 seconds to all my routers at home/office etc.. with no lag at all.
5>the 4g zzzz's when not in use. While usually it 'awakes' quite easily, at times it wont; like when I am using voice action. Any way of un'zzzing' it? Dont know about that I dont mind it, it always wakes up when I need it.
6>how to get the auto-rotate screen on/off switch by the wifi/4g/gps/bluetooth options on the notification screen. The samsung galaxy att has it installed already....Thats something I would love too.
----------------
2: The graphics are a little bit too big and simple. HTC sense is def better. Sometimes I feel like they made the phone for an old woman. Right but dosn't bother me, because I can see it from far away, very useful when driving.
3. When texting using swype the text box bounces up and down as the word suggestions are given. I have found that annoying.By me its shows side by side on very nice strip top of keyboard, make sure your'e using swype version 3.25.91.... maybe its outdated by you.
4. Theres no restart option just shut downYou can add a restart widget on the home screen if it helps.
Only real con is the Longest android but still short battery life but I solved this with $12 Bucks, see here
