[Rhavon]

I've recently purchased the Sony PRST1 and have managed to successfully root it. I'm running Gingerbread Market and whilst I've been able to download Moon+ reader easily and it works great, Market won't show the IVONA HQ app (and associated voices) nor Calibre Companion (both of which I want to download). I've read a lot of [confusing to me] posts and threads and being VERY new to all this (and Android), I'm finding it all quite overwhelming.

Is there a better app than Market for the PRST1? Is my version not running correctly or have others had the same problem? Is there a place to download various apk files for apps, thereby removing the complications and need for a second android device?

Thanks in advance.
