At last, at long last, the popular Twitter client Gravity has gained large fonts, for use by those like me who (ahem) have less than 20:20 vision in our advancing years. You'll need to go online in Gravity, move to the start page and click on the 'alpha' (and 'experimental') version 1.20 build 5570, but don't worry, it works just fine. You also gain, as shown below, the ability to have a different (e.g. a white) theme/backdrop, again greatly aiding visibility. v1.20 works fine on all S60 3rd Edition and 5th Edition phones.

Thanks to Mobile Jorge for the heads up. Also for the direct link to the SISx file for this 1.20 alpha release. See also the Gravity home page!
