Skype makes the news again this week - it has released its full-fledged Windows Mobile phone software (downloadable from this link), which was in beta so far. Also, Apple approved Skype 1.1 for the iPhone and iPod. But Skype isn't just making people happy; it is causing disappointment too.

Since I reported on Skype reaching Blackberry some time back, following a Skype press release, I kept receiving comments from disappointed BlackBerry users, most of whom not knowing where to direct their blame to. Alex commented today, "I think this is rubbish. Yes, there was a call for beta testers on the skype lite forum for Bold owners. However, that was all, and the suggested release date passed by, and NO update at all." My only reaction is to suggest patience. I wish a reaction comes from inside Skype itself. Meanwhile, Blackberry users can benefit from the advantages of VoIP through other services like Vopium, Truphone, Yeigo, Raketu etc. Find a list of those applications there.

Blackberry is the most popular smartphone for enterprises. Yet, it has been lagging behind in terms of VoIP implementation. This is mainly due to a lack of adequate solutions and applications for RIM's machines. Blackberry is nowadays knowing unprecedented popularity, and many VoIP providers are including it into their supported handset lists.

Agito, an enterprise communication solutions provider, aims at capitalizing on Blackberry's position on the enterprise market. Up to now, enterprises using Blackberry have had to content themselves with incomplete and often expensive solutions. Agito now provides a Blackberry solution that includes PBX functionalities in its RoamAnywhere router and an intelligent VoIP application for Blackberry handsets. This way, calls are shifted from cellular to Wi-Fi, thereby saving a lot on business communication. Other benefits include enhanced mobile PBX capabilities, with some PBX functionality present on Blackberry handsets, unified communications benefits, low investment on hardware, among others.

Mobile VoIP telephony is looking out for its independence from restrictive Wi-Fi and expensive 3G, although it is nice and and at times economical to be able to use them from time to time. Nimbuzz is among those that believe that VoIP should be available everywhere, not only within 3G and Wi-Fi networks. Nimbuzz wants to be a truly mass-market application. It is a mobile social communication application that allows VoIP calls and chat across many IM platforms and social networks. It has the advantage of running on all Internet-capable handsets and can smartly shift between Wi-Fi, 3G and mobile networks.

Now Nimbuzz works together with Voxbone, which is a provider of worldwide, local and toll-free numbers. Voxbone has its own own private intercontinental VoIP network, over which it offers the numbers. The Nimbuzz-Voxbone partnership can be very powerful for us users. When Nimbuzz adds the DID numbers to its service, mobile VoIP - with its tremendous advantage of mass saving on phone calls, plus the features - can be offered outside Internet connectivity areas and 3G networks in more than 50 countries. You get to do that with any handset that is Internet-enabled. Nimbuzz hasn't been very talkative about that, but watch out for the release.

Switching to Google Voice might be less than smooth for most, and squarely costly for many. This is because the ubiquitous number you will get won't be the one you already have, which everyone knows. Google figured this out, and is working on addressing the issue of number portability. They intend to offer number portability as a general feature with Google Voice. This will imply that you can take your home or even mobile number to be registered as your Google Voice number. Read more
