Loved on Blackberry. iPhone OK.

I loved ubersocial and its features when I had my Blackberry. Sadly a lot of them are not offered for iPhone, as of yet. Needs push notifications and theme options. Also needs work on location determination ( no way to enable ). No problems with loading tweets on my end tho.
Its not a bad app and has potential to be a top contender. It just needs work.
