The Guardian’s Bike Blog reviews CycleStreets, a free iPhone app; it’s essentially turn-by-turn navigation for cyclists. UK-only, using OpenStreetMap data. Via Steve Chilton.

Avenza has announced PDF Maps, a geospatial PDF reader (i.e., PDFs with embedded spatial data). Universal app for both iPhone and iPad.

GeoLife has released a free version of its turn-by-turn navigation software for the iPhone and iPad. Navfree covers the UK and Ireland, is a universal app, and uses OSM data (which presumably explains the free part; its other apps cost money). Via Geospatial News.

Something I’m going to have to try myself: UpNext, a 3D cities mapping app (eight U.S. cities so far), again in both iPhone and iPad versions. Free. There are video demos for each version: iPad, iPhone. More at TechCrunch. Via Ed Parsons.
