The using the same url scheme for twitterific and twitterific premium doesnt work for me. I have installed twitterific, and it worked. Then uninstalled it and installed the premium. It doesn't recognize that url scheme.
In his [REDACTED] post that publicly demo'd the url schemes Craig Hockenberry mentions this issue:

Also, be aware that deleting an application can sometimes leave the URL registration database in a state where it no longer recognizes a scheme (rdar://problem/6045562). This only happens when two applications support the same URL scheme, so you can avoid the problem by using a unique scheme name. Please use the Radar bug ID# for a “me too” bug report if this becomes a problem in your own application.
