Use RSSRunner, probably the best RSS reader I have seen but it is an iPhone only application. Ryan Petrich released ForceFull and it works GREAT with RssRunner -- it looks like a native iPad application. ForceFull is free and it works better than RetinaPad which upscales iPhone apps to Retina resolution. ForceFull uses a heuristics approach and looks better with RssRunner (I own RetinaPad). RSSRunner will import opml feed exports too. I highly recommend it and I use it.
ForceFull is freely available in Cydia but you have to be JB.
