using PimBackUp trying to extract text messages from damaged phone

[iHateXmas]

OK, so my old phone was basically destroyed, but i have lots of important messages etc that i need to extract. i used PPCPimBackUP and i got all the files but they were saved as PIB file. Now, i found out that .PIB files are basically zip files. i extracted those and the largest file (the one with the important texts etc) was a PBM file. I've tried several programs but to no avail to open this in a readable form. If anyone can point me to any help, or if you have a different program that you've used to transfer these messages i would greatly appreciate it.
