SNAPin.

"SNAPin isn’t a sexy, in-your-face application, but works almost unobtrusively in the background on your handset. It’ll be put on your phone by your operator and it’ll simply help you get the most out of your handset... If SNAPin detects the wrong settings, it’ll just fix them with an Over The Air (OTA) update. You can even then go and mess them up again and it’ll just quietly correct them. The operator even has the choice of deciding to fix stuff in the background or opting to tell you what a nice company they are as they’ve solved the problem for you... If you dial the operator’s customer service number, your phone prompts you with a pop up menu to help yourself. It offers you choices of top issues like billing enquiries or upgrade options. Then it gives you the information on the phone screen... SNAPin just announced at 3GSM a big trial with UK operator, Orange."
