ANy better solutions?

What has more then likely happened is a manufactured defect and happens often when your phone goes through temperature changes (cold to warm and warm to cold) being the winter season right now. What I have always had luck with is taking the battery, SIM card and SD card out of your phone and leaving it anywhere from 10 - 20 min. I imagine that you have already tried this but for whatever reason the longer you leave it apart the better the chances are of it working again. If you haven't tried this, simply turn your phone off take out all of the above and count 20 seconds then put it back together again.
I know this may sound stupid but I worked in Cellular Sales for over 6 years and 9 times out of 10 that's all it took to start working again.
If none of the above works then check for corrosion and other signs of water damage (The little white circular dot indicates if its water damaged if it has turned a deep red or pink) if this is the case then your phone is toast and will not be covered under any warranty (extended or manufactures) and I'm sorry if this is the case.
Anyway hopefully this was of some help to either fixing your problem or giving you the correct details needed.
All the best

drivers are not safer way to unlock any phone. unlocking through drivers is also a tedious process. you no need any physical connectivity when you unlock through codes as you do in cables. also while unlocking through drivers there are chances of dataloss or hardware crash when any one process goes wrong. so its alway better to unlock your phone through codes. its the simple and easier way to unlock your phone. i got the codes from here TheUnlockArena to unlock my phone. you can get one to unlock your phone.are not safer way to unlock any phone. unlocking through cables is also a tedious process. you no need any physical connectivity when you unlock through codes as you do in cables. also while unlocking through cables there are chances of dataloss or hardware crash when any one process goes wrong. so its alway better to unlock your phone through codes. its the simple and easier way to unlock your phone. i got the codes from here Mobileunlocker.com to unlock my phone. you can get one to unlock your phone.

there are several sites where you can type in your IMEI Number and they will generate unlock code for you, normally about 7, you only have about 3 - 5 goes at it then the phone will hardlock, I have tried most of the codes to test them,the answer is "none of them work" go to a phone shop and they will unlock it for, its the easiest way out

hi there is a solution to jailbreak and unlock your iphone with redsn0w but i would wait for a better solution as this one up dates your baseband to an ipod baseband and you will not be able to update with itunes anymore and any warranty is void.
As for the websites that say they can unlock your phone they are all scams they will only tell you to unlock with redsn0w any phone numbers they give you are not real i have tried i tested one out.
my iphone is 4.1 aswell and i would not unlock with this solution on my phone and i work unlocking phone for a living hope this helps and by the way iphone unlocking solutions are given to you free by dev team and other unlockers.

Sounds like your phone has a hardware problem.
But if your remove the battery and let it sit for a while, then replace the battery, see if it is better.

If not, take it back to your provider and they should replace the phone.
If your provider won;t replace it the manufacturer should.

you gotta call customer support, certain phones will lock you out and you have to call customer support (your carrier's) and the representitive will give you a new unlock code
