Its probably due to model name correction; previously it was identified as Nexus S; now its HD2 (or more percisely, a "generic HTC HD2")
If you want to change to Nexus S you will have to install
Build.prop Editor
Then modify the key=value pairs as following:
Code:
ro.product.model=Nexus S
ro.product.manufacturer=samsung
ro.build.fingerprint=google/soju/crespo:2.3.4/GRJ22/121341:user/release-keys
ro.build.description=soju-user 2.3.4 GRJ22 121341 release-keys
WARNING
Obviously if you install an app and it will crash its because its not compatible/been improperly installed due to the fake device configuration.
Some applications, especially from the Market use the device information to perform different installation routines (sdcard mount points, OpenGL compression methods, etc...), so use at your own risk
