I’ve posted here periodically about my enthusiasm for Blackberry, specifically the Bold 9000 that I’ve had since the beginning of the year. One of the reasons I held on to my old 7100 for so long was that I was waiting for Telstra to release a NextG Blackberry, which they finally did. And then I was mulling over whether to get the Bold or the Storm, a decision which was ultimately made for me by Vodafone’s exclusivity with the Storm in Australia.

Of course, during this period I didn’t use the 7100 as a primary device – at least I hadn’t for quite a while. Instead I’d revolved through the Locatrix handset de jour – whether it be an iPhone, N95, or whatever – as my primary handset. The Blackberry was only a secondary device, for the sole purpose of e-mail. And then in February I migrated to the Bold as my sole device, and its been mostly a happy marriage.

However I have been travelling so much this year and – quite belatedly – working with local SIM cards to reduce roaming costs wherever I can. This has meant, however, that I’m accumulating a shed full of “other” numbers which I maintain active, and use whenever I’m in the relevant country. This week, for example is a HKCSL 3G prepaid service, which I’ve had in my trusty E51.

Ironically, this has meant that I’m back to a dual-device personality – being as attached to e-mail as I am, the Blackberry is usually in my pocket. But locally working with the Hong Kong number – we’ve got an office DID here now, so its how I’m connecting with the team in Australia to save money – I’m carrying and using a second phone. As a primary device, this week, anyway.

So ironically, it’s Black to the future – despite my passion for the Blackberry solution, it’s still not meeting every use case I come up with.

So any plans for dual SIM devices, Research in Motion?
