Yes, its now possible to do it, right on your android phone. You’ll be able to see every tower that’s connected to you, their individual strengths, and your overall connection strength.
On 3G or CDMA networks, you’ll only get to see one tower, due to an Android OS limitation, but you can still know where your strongest tower is located, and how you’re doing on connection. Pretty nifty when it comes to finding the best location in your work or at home when you experience weak signals.
Also, you can Monitor Android Battery Power usage.
For best results, switch on both data service 2G (“EDGE”) and 3G connections (if your networks supports both).
