Ok this is a good deal for someone who just wants blackberry or data e.g. for messenger only.
Deal is Buy on 12 month contract (18 and 24 availiable but no discount on phone but rental a bit cheaper).
Get 8520 for £97.50 - leaves £52.50 over.
Therefore 12x £14.39 = £172.68 + £97.50 - £150 Quidco = £120.18 for year INC PHONE
OR = £10.01 a month inc cost of phone.
Or if you prefer the 8900:
12 x £14.39 = £172.68 + £127.50 - £150 Quidco = £150.18 for year INC PHONE
OR = £12.52 a month inc cost of phone.
Not bad for blackberry data plus 500mb for browsing or messenger etc.
