The title says it all. I have a G1 running the latest BiffMod (2.1, love it!). The only trouble comes when I use the Biff gapp zip. I can sync my contacts and email, but I can't sync my calendar. So I flashed a different gapp. Now my calendar and contacts work. Buuut my native gmail app FC's. I've found that I can work around this by installing K-9 email. So if worse comes to worse, no biggie, but I'm thinking that if I combine the working gmail.apk file into the gapp zip with the defective gmail app I'll have a winner....hopefully. Anyone know how to modify gapp zips? I tried copying and pasting but it said something about a signature being needed when I attempt to flash. Thanks in advance for your help!
