Yup thats full fat Android 2.1 Hero, on Lemon
so happy days you are the owner of Hero 2.1.......
Full factory reset? I did mine yesterday after similar performance issues has helped alot....ALSO have you checked how it's connecting to the tower?
Menu, Wireless & Networks, Mobile Networks, Network Mode, set it to GSM only, you might be between 2 towers one giving HDPSA the other Edge or similar if it cant decide it might be flicking between the 2 cells, I know you say the iPoo dosent do it, but I dont know how they handle that sort of thing....anyway 'tis a thought and worth a go
