That was fixed in MonoTouch 4.2.2 [1] and recent 4.9.x alphas. Of
course the monotouch.dll required to support the iOS5 API will be
larger (than before) so not linking will result in even larger
applications (i.e. linking will become even more important).

Another common reason for large applications on device is using FAT
binaries (i.e. armv6 + armv7).

Regards,
Sebastien
