Somewhat OT: What can break on a cell phone?

From: Joerg on 11 Jul 2010 10:57 Gents, My trusty old Nokia 2115i only gets one and very occasionally two bars. It does connect but calls fail. Can't get a new one before the next trip because it needs to be sent from VirginMobile and the local stores don't have any that would work. Is there some "typical" problem that happens with such phones, like bad solder joints? Or are there any issues with the Sprint network these days? That's what it uses. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam. Use another domain or send PM.

Then again, my also quite old Nokia 6015i is still going strong, original battery! Heh, while googling about them, I saw a list of AT commands. Maybe you can hack a serial/USB connection to it and run some diagnostics on the modem? Tim -- Deep Friar: a very philosophical monk. Website: http://webpages.charter.net/dawill/tmoranwms

No Chinatowns where you live? I can go to any number of little cell phone outlets and get pretty much any phone unlocked-- usually the asking price is around $25 cash. You can do it yourself too, but there is some risk of bricking the phone, depending on type. Best regards, Spehro Pefhany -- "it's the network..."
