Time to leave the iPhone cycle. Currently using an iPhone 4. My plan is expiring in about two months and I've had my eyes on the Xperia Sola. Question is: What phone has similar size to the iPhone and better specs? (I'm not interested in the S3/Nexus size phones). What Android phones will blow me away? I'm really interested in trying an android, but once again, size about the same as iPhone (3.5 - 3.8" ish) Will the Sola be sufficient, or is it actually a downgrade from the iPhone 4?
