It's that day – the day you can walk into a high street store and order the upcoming Samsung Galaxy S5. The hands-on got a four-star review, so it's certainly worth considering. Especially if you like the idea of monitoring your heart rate constantly or you do a lot of online business via PayPal.If you do opt for one, you can get the phone at Carphone Warehouse, via Vodafone, for £42 per month, with the device coming free. Alternatively, you can hunt around for your own SIM deal and get the phone for £579.One key thing to note regarding pre-orders is that arrival dates will vary depending on the colour you opt for. Play it safe with Shimmer White and Charcoal Black and you'll have the phone on 11 April. Be more daring and opt for Electric Blue and you are looking at 22 April. Go for Copper Gold and you can forget about your new phone until 20 May. Yes, really.Pre-registration numbers have already beaten those for the S4 last year, so it looks like buyers aren't too concerned about the lack of any significant strides forward in the new phone. It's the latest Galaxy S, that's all that matters.'The S5 looks set to become a record breaking handset for Samsung at a key time in the mobile calendar as several major manufacturers launch handsets within weeks of one another,' Carphone Warehouse said. 'Our early pre-registration figures for this handset were off the charts and we're expecting web traffic this evening to be high as Samsung’s loyal fans log on to place their orders.'So if you want one, act now. Just think very carefully about which colour you want, especially if you want the phone in your hand in the next couple of weeks.
