Hello! I have recently experienced problems with my 3G iPhone. 1. The phone is unable to find GPS signal. I used tomtom to search for gps signal earlyer today and left it in the window, for about 15 min. When I try to use the map app it doesen´t get a signal there either. 2. The battery has decreased battery life. I charged it all night, and now it only last a few hours. I don't know why, and even when the screen is locked the percentages just flys away. I have to charge it several times a day. What I find so wierd is that in last week it used to last a couple of days, before I had to charge it. I can give you an example of what happend today. I connected to a WI-FI network, to cheak the weather. When I started I had 63%. 5 min after, when I was done, I had 54%. I find it hard to belive that the battery needs replacement, sence the phone is only 4 months old. I'm from Norway, so I apologize for any typos.
