Hi, I am new to BlackBerry world and I am trying to add BBWeather to my phone. However, it gives me an invalid tunnel name error. I looked into the source code and I noticed that it does not have the updated link for Weather SOAP. I fixed this issue and it works fine in simulator but i cannot add to my phone for RIM Signature issue. Can some one update the SOAP link
WEATHER_SOAP_REST = "&prod=xoap&par=1006814500&key=ee4ffa68f8bf99cd&un it=";

by adding
&link=xoap between &prod=xoap and &par=1006814500

Do I have to buy RIM Signatures for developing applications?
