i ordered/received and am using a
1340 mAh GSM Diamond battery from expansys.com. it's an OEM HTC battery that's the same size/spec as the one we're using in our Diamonds. The only downside is that it comes with a GSM battery cover. i sold my cover for $12 which put my net cost to $48. it's been working just fine as of today. as far as i know, there's no difference between the GSM and CDMA batteries...
