Disable GO SMS Pro weekly nag messages About once a week, GO SMS Pro "receives" (I don't know if it comes from somewhere or if it's written into the application) a nag message from "c10000@go.chat" along the lines of:


  Most of users loves GO SMS Pro because of themes. Thinking of cool &amp; stylish messaging experience? Try out another bestseller: ColorGlass Theme&nbsp; (Apply it through menu->theme)


It's extremely annoying. I believe I've logged out of GO Chat (though it tends to log itself back in without asking and won't stay disconnected), and have tried going through the app's settings multiple times without finding any way to kill these notifications. They're driving me batty.
I'm pretty sure this will work but I can't test it fully because I never updated Go SMS to the "nagging" new version after reading all the complaints in the reviews...

You have to be rooted.  If you are, install Root Firewall Free and block internet traffic for Go SMS.  I don't get those nagging reminders but I tried it and I was still able to send and receive SMS messages but I could not use features that use the internet like the Go Chat. If you want to download a new theme or use one of the data dependent service periodically you can just toggle the block off from the firewall app and put it back on when you are done. Obviously this won't help you if you use those data dependent extra services regularly.

Alternatively, if you are not rooted you can revert back to version 4.56 of Go SMS.  You can download this version directly on the Go SMS website.  This is the version I have and I don't get any of those annoying nags.  When I started typing this answer I didn't think they'd post past version but now that I see that they do I'd say this is probably the better option.
