Not to be outdone by the Helio Ocean addicts, one intrepid hacker writes us to let us know that the Sidekick (tested on the Sidekick iD and Sidekick 3) is also capable of running Opera Mini and he got it working. Don’t expect to see this in the catalog any time soon though, as it is doubtful T-Mobile would allow it. Currently it’s only available for people in the developer community which you’ll need to be a Java programmer in order to get into. But then again, unlike the Helio Ocean, the Sidekick already has an awesome browser that works and doesn’t really need replacing.
