Summary: Yes, you can add external memory to your HTC Explorer, but its still totally useless. The internal memory is extremely low, most Apps can only be downloaded on internal memory, and after installing the second App, your phone is dead with false messages. Furthermore, most possibly due to the 'Always' short of memory problem, Apps go and come back occasionally. SD is working, but you cant find the Apps on it.
