There has been much speculation over microSD memory card access on Windows Phone 7 handsets. The Samsung Omnia 7 has an accessible slot underneath the battery cover that will allow users to expand storage. However, it won’t let you use it as removable storage given the limitations of WP7.
Unfortunately, the HTC HD7 does not have the same accessibility. Behind the battery cover only reveals a slot for the sim card only with no memory card accessibility to be found. This is somewhat disappointing if you only buy a HTC HD7 with 8GB storage. It is less of a deal breaker for those who have handsets with 16GB storage. Check out the pictures beneath the HTC HD7 hood below.
