I have read a few threads, the main getting started one mentions that you cant unlock DB3150 phones to all networks and I was just wondering if this information is up to date (as its a good 9+ months old)

XS++:

04:31:51| Platform: DB3150
04:31:51| EROM CID: 52

Is this a lost cause for unlocking, Can I take it into a store to get it done if I cant do it myself or is it just one of those phones thats stuck with its network forever?

Thanks
