You use the "Manager" app to remove/uninstall programs (in writable phone memory or the memory card)
With built-in applications in ROM (Read-Only Memory) that option is not available (and wouldn't make any sense, because you wouldn't be able to get any more space either, because you can't write anything else to ROM, either).
Whoever you are N/A, you helped me earlier, and reading this has just helped again...
I installed some demo stuff t see if i liked it... stuck it on the memory card... could I remove it... could I hell!! Spent the best part of 4 hours trying to work it out... no tea, Mrs Pi**ed off... and then I find this.
