I have been having a few issues with the phone recently.
My wi-fi doesn't work, I can't connect with the wi-fi of my house. Sometimes it will be stuck with obtining the ip adress, or says connecting but no luck.
I don't have bluetooth anymore, it says turning bluetooth on (the key is grey not blue).. and then goes back off. I had tried with the botton from the notification bar but it doesn't work either.
I don't have any network connection (3G, G, H, H+), the phone works fine with incoming/outgoing calls, sms but not internet.
I don't know what to do, I have been using this version from a long time and never had problems.
