Dolphin Standard Read it Later question

[wt.pm]

I am using Android 1.5, and the standard Dolphin browser, I can click the "read it later" button and it says "page saved". Now I also have read it later on my FireFox, how do I sign into my account, so I can actually use the function. I can't even locate the pages that I have saved using my phone, there is only one r-i-l button, and it is the save button. I have tried to download the r-i-l app from appbrain, but my phone says "app not found" (as usual with all the good apps). So do I have to wait for Motorola and AT&T to update my phone, or am I just missing something?
