The Arc has been one of  Sony Ericsson’s best smartphones this year. It was slim, as it was supposed to be, since most of their competition had phones like that already, and it was stylish. Design is still one of Sony’s strong suit, but it doesn’t go well with thick phones, which is how most of their phones still are. But I imagine they will be pushing other slim phones in 2012.

The Arc HD is not only proof of that, but it’s also a bit of proof that Sony Ericsson is finally understanding that they need to be on the edge with hardware specs, too. Here are the rumored specs for it:

  • Android 2.3 Gingerbread
  • 4.3 inch 720p HD display
  • 1.5 GHz dual-core Snapdragon S3 CPU
  • 12 MP camera with FullHD recording
  • 1 GB RAM, 16 or 32 GB internal storage
  • HDMI port

Depending on the launch date, the dual core 1.5 Ghz S3 processor is not too bad if the phones arrives like until February, but if it arrives like sometime in March or later, then I would say SE still isn’t taking hardware as seriously as they should. By then we’ll see dual core S4 (Krait), Tegra 3, and OMAP 4460 (dual core 1.8 Ghz ) processors.

The good news is that it will have a 720p HD display, which means it will be 100% ready for Android 4.0. The current specs don’t say it will have Android 4.0, but I’d bet for it rather than against it. SE has been good at least delivering the latest version of Android on their phones with their Xperia line, and I’m not expecting them to stop any soon.

But again, the date of launch matters. If it’s early January, it’s very possible it won’t have Android 4.0, but that would be a pretty big mistake. I wish manufacturers would realize that it’s worth waiting one more month to launch their product with the new major version of Android, rather than be a month early, but with a 6 months old version (if not older).

We should get the full details about the Sony Ericsson Arc HD and its official announcement at CES next year.
