I have a blackberry 8520 curve with W-FI on it but no internet service provider, BUT, I do have wirless internet at home. I tried to connect everysingle way I can think of through by blackberry and it wont let me go to the internet unless I upgrade (buy it).
so you have WiFi in your home but not the data plan? If you go to manage connections I know you can connect to WiFi there, but if you are not in the range of a hotspot or connection and sans data plan, you will not be able to get on the Internet.
but i have perfect wirless connection with my wireless laptops and i have wi-fi on my phone and i did change it to that and try to connect but still no)'.
