Hello everyone, Attached is the screen shot of my iphone. You can see there is a phone-like symbol on the top right corner between alarm and battery percentage. I was talking on the phone when a second line came. But the phone didn't display the options that to hold and answer (and stuff like this). Thus I couldn't do anything except continue talking on the phone. After I finished the call, this symbol appeared and never went away. I tried reboot and taking out the SIM. No luck. Then I started question my memory. We normally don't have that symbol when we are not making calls, right? Can I take it away? I know it is not a big deal, you know, it is just weird. Thank you~~ ================================================= Problem Solved by a Reset (Reset All Settings) Thank you everyone! Problem solved! I did a reset, the "Reset All Settings" without loosing all data. Everything went back to normal. More info: It is jailbroken, iPhone 3GS 3.1.2 Firmware 5.11.07. I used Blackra1n to jailbreak. I got the Internet Tethering back. I also have GV as someone mentioned. After the reset, everything went normal. Well, the only problem was the weird icon. Again, thank you all.
