Chris Miller announced this afternoon the return of IdoCheckin for Lotusphere 2010.   I regularly use Brightkite , and I recently had a problem configuring the Brightkite for Blackberry application on to my Blackberry Tour, so I thought now would be a good time to share ( I never determined the cause of the problem, as you will see below others had the same issue, so I am not saying you will have the problem, but if you do hope this helps)  Every time I tried to login to Brightkite, I received the following error on my Blackberry:

Network Error: Your network coverage is insuffucient for a data connection to Brightkite.  Try again later.

I found this a  bit odd since my network coverage was fine, and to the best of my knowledge there were no policies on the BES server preventing me from using the GPS, or the application itself.  I tried uninstalling, rebooting and reinstalling same result. Finally after searching around a little I found the answer in a conversation on Brightkite.  The solution was to check the box for “Disable Connection Check” I am not really sure what the “Connection Check” is, and it gives a nasty warning about why disabling it is bad”

Disabling the network connection check may result in errors.  It is HIGHLY recommended that you leave this enabled!!

but I ignored that and continued and sure enough it fixed the problem!
