Unknown icons appeared in status bar - can't get rid of them

http://androidforums.com – Hi, I have a ZTE Blade with Swedish Snow RLS7. Yesterday some strange icons appeared in the status bar and I can't get rid of them. Unfortunately, I can neither link nor add an image, which will make it hard to identify the icons... The three icons are at the top left in the status bar (looks like a home icon, a settings icon and an arrow). I installed a couple of apps for tracking cell phone coverage yesterday, then uninstalled them. That is possibly the cause of the problem, but reinstalling and uninstalling again makes no difference. Restarting the phone also makes no difference. Any (General)
