Did you bother checking if you already had the Phone Lib installed?
I'm sure it comes standard with the B4A installation and the one you have copied is an older version.
Hmmm...maybe I over wrote my old phone lib because I copied these phone.zip files to my extras folder, not my internal lib folder as Erel stated. But I don't see an internal lib folder...?
I removed the two phone lib files from my extras folder and was able to compile again. So that was the problem. Now the problem is that the two files in the phone.zip file are to be copied (according to Erel) to the b4a internal lib folder but I don't see it.
I'm away from my PC at t moment, so I can't get the phone lib ver but I think you solved it for me. I didn't realize the phone lib was already in the internal lib, so I didn't need to add it as an external one.
