I've found 'Manga Browser, downloader, Reader' or 'manga bdr' to be waay better then the rest of them man, to get the manga is a little bit of a pain but you get to use all the sources you want and you can do download now and read later stuff as well. There's a lite version that you can check out.
ANDROID!!! I miss my droid soo much! trust me its a platform thats gone far beyond iphone, the only app i will recommend because it's the only one you'll need is 'Manga Browser' it's kick ass, best app i've ever used for manga. As for other things, i think you'll find the adroid market has reached up to the ridiculous scale, i prefer it to appstore as you get a lot more high level apps for free, if you can put asside the lack of games compared to the iphone it has, in my opinion a better and cheaper market. Stuff there are a lot cheaper then on the iphone and i think you might like the widgets as well they're pretty cool, but be warned if you have too many your phone will get drunk and hung over on battery juice. All in all if you had an iphone and not yet an android i'd try and get both experiances. I myself moved from android to iphone just a couple of months ago, but still even though it seems like im a major droid boy the iphone does have its perks, don't get me wrong analyse things like an adult rather as a kid, tech is tech...now excuse me while i post some boobies..haha..boooobies
