That's right. When Game did not have stock I bought it for a few hundred rand extra from Cellucity. And I'm very pleased. It has a solid feel to it. You would think that they would cut corners with e.g. inaccurate sensors, but they didn't. The only problem I found is that it will not make data connections over MTN (and CellC ?), presumably because the APN has been hard coded. I also think people used to capacitive touchscreen and/or full keyboard will be disappointed, but that's not me. > Tech Specs: > * Processor: Qualcomm 528MHz > * OS: Android OS, v2.1 > * Screen: TFT touchscreen, 65K colors, 240 x 320 pixels, 2.8 inches, > Accelerometer sensor for auto-rotate UI > * Application: SMS (threaded view), MMS, Email, IM > * Connection: GPRS Class 10 (4 +1 / 3 +2 slots), 32-48 kbps, EDGE > Class 10, 236.8 kbps, HSDPA 3.6 Mbps, Wi-Fi 802.11 b / g, Bluetooth > v2.0 with A2DPUSB v2.0 / Model: Full TouchScreen Candybar > * Internal Memory: 512MB ROM / 256MB RAM > * External Memory: microSD (Max up to 16GB) > * Camera: 3:15 MP, 2048×1536 Banner, autofocus, video Support > * Network: HSDPA 7.2Mbps (3.5G) / WCDMA 900/2100MHz / GSM Triband > 900/1800/1900MHz > * Battery: Li-Ion 1200 mAh > * Color Options: Black > * Browser: HTML, JAVA MIDP 2.0 > * Dimension: 100 x 56 x 14mm > * Weight: 110g > * Talk Time: up to 270 mins > * Standby Time: up to 270 hours > > Details ripped from here: http://www.androidza.co.za/ > > / Grant > > ___ > Talk-ZA mailing list > Talk-ZA@openstreetmap.org > http://lists.openstreetmap.org/listinfo/talk-za > ___ Talk-ZA mailing list Talk-ZA@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-za

Hi Nic What phone at Game are you referring to? I have been looking at getting a new phone with GPS, and R1000.00 seems reasonable to pay. Thanks Anton ___ Talk-ZA mailing list Talk-ZA@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-za

Hello, I've followed OSM for a while now, although I contribute less than I would like to. Anyway, I've been thinking of the best way to collect house numbers in my area. I explain below the "ideal app" I wanted, which my lack of coding skills prevents me from developing myself. If anyone on this list think it's worth writing the app, I'd be glad to see it working! 2011/1/23 Nic Roets : > A typical 2 digit house number takes only 3 key > strokes. > http://help.openstreetmap.org/questions/1385/what-is-the-best-mobile-application-for-large-scale-house-number-collection > > But it's still not fast enough to collect every house number when > cycling at 20km/h. Rather than inputting the numbers through a keyboard, does it seem do-able to record your voice as you cycle? As you cycle, you would go: "2", "4", "6".. etc, as you see the houses (I'm assuming you focus on one side of the road at a time). When back home, you could use a speech recognition software (this, perhaps: http://cmusphinx.sourceforge.net/) to "write" the numbers, and a specialized little tool to give a timestamp to each written number (this could help: http://www.billposer.org/Software/pause.html). From there, it should be easy to cross-reference the timestamps of the house numbers with the GPS track and create an OSM file for the house numbers (slightly offset to the right of the original track). If that works, there's no need to restrict ourselves to house numbers. If number 17 is a church, you could record: "17, worship, christian", and from there it doesn't seem impossible to generate . Does this sound reasonable (and does it sound like an improvement from typing?), or am I missing a basic problem?

If my GPS takes me to 23 Long Street instead of 29 Long Street, that's not so bad. If my GPS doesn't know which side or which end of the street to go to, that's less impressive. -- David Richfield e^(πi)+1=0 ___ Talk-ZA mailing list Talk-ZA@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-za

Thanks Philip, The two selected nodes are the starting and ending points. I know that interpolation can be out by tens of meters, due to varying plot sizes. Even worse is that I intend to use even interpolation for suburbs where the increment is 4 (for example, Nominatim thinks that 328 Edna,Pretoria exists, while it doesn't). But collecting these details will make the projectsmuch too large. I'll help you with writing the code that generates the parallel ways. It will take a list of lat/long pairs (the road) and produces another list of lat/long pairs (the new way). Assuming it's a Josm plugin, I'll do it in Java.
