Same here only records ME not the other party (although it picked up my sisters phone ringing 30ft away holy crap thats a good mic but not good enough to pick up the ear piece.
Since it only records me its no more useful than the built in app so I will stick with the built in app for now.
At first I was confused by this lack of recording the conversation issue. I mean Every phone I have ever owned was capable of recording both sides just fine.
Then it hit me. Every phone I have ever had before now was a SANYO for the most part. Apparently its a very Uncommon app just common to sanyo
even my old black and white sanyo 6200 did this. (I use it as an answering machine eliminating the need for voicemail for the most part)
I just wish Youmail would work with sprint but sprint treats it as call forwarding and at 20cents a minute well it costs more than my monthly bill each month. Grrr
